0 steps two weeks ago and before?

I’ve just noticed that I have 0 steps counted 2 weeks ago (25 October) and all days before.
I wanted to open my old chest…
It’s a bus or data are deleted after 2
weeks ?

Thank you for your answer.

Up. :bowing_man:t4:‍♂️ This is a bug or not ?

Fit tower chests can only kept for 7 days, however, the step count should be saved there as a record. Can you please let me know your game id so I can double check?

Thank you for your answer.
